[Pywps-dev] Can't get XML output's execution ( pyWPS + Owslib )

[Mariano Kaimakamian]

Hello guys:
My name is Mariano and bothering you because I need some guidance; I did a
research but I didn't find any solution.
I'm using pyWPS 3.2.1 (on Ubuntu 12.04.5 LTS) together with Owslib 0.8.9 as
a client, and I'm experiencing some issues when I try to get the response's
xml after pyWPS executes a process; I'm not pretty sure if the problem is
Owslib related but if someone knows something about it, please, let me know.

The process works as it is expected and I can get the output's object that
pyWPS returns (WPSExecution, an owslib's object) if I send the request
omitting the output parameter; however, when I explicitly include that
parameter to get xml generated, the xml is created but without the output.

Take a look, please:

# Setting service and some values
wps = WebProcessingService('http://myDomain/wps', verbose=True)
input_parameters = [
    ("exe_uuid_input", "uuid"), ("pla_uuid_input", "uuid2"),
    ("literal_input", "foobar"), ("sleep", "2"),
    ("sender_address_input", "info at somewhere.com.ar"),
    ("sender_psw_input", "Some input"),
    ("mail_to_input", "info at somewhere.com.ar")
]

# Execution...
# Accordingly to owslib documentation, "output" is optional identifier
which makes owslib to return the process output as a hyperlink reference...
that means that an xml is generated.

execution = wps.execute(

"proceso_test_2015122_version_test_2015122_4f5a18d2-dfee-4167-a427-ab2e5d7d0bea",
    input_parameters,

output="proceso_test_2015122_version_test_2015122_4f5a18d2-dfee-4167-a427-ab2e5d7d0bea"
)

Here is the xml created:

<?xml version="1.0" encoding="utf-8"?>

accepted</wps:ProcessAccepted>
    </wps:Status>
</wps:ExecuteResponse>

As you can see, there is no output and the status is ProcessAccepted, when
the owslib's object -if I omit the output parameters- confirms the success
of the operation.

That's all guys.
Thanks in advance for your time and for any comment; let me know if you
need more information.

Reagrds,
Mariano
